Chemical structure and synthesis
-
The molecular formula:
C12H10O -
Block diagram: It is a molecule in which two benzene rings are connected via an oxygen bridge (Ph–O–Ph).
-
Synthesis: Diphenyloxide can be obtained by sulfonation of phenol followed by reduction or direct thermal dimerization of phenol under appropriate conditions. The synthesis technology makes it possible to achieve high purity of the final product.
Physico-chemical properties
-
Appearance: Usually a colorless or light yellowish liquid or crystalline product.
-
Boiling point: It is high, about 260-280 °C, which makes it suitable for use in high temperature conditions.
-
Solubility: It is slightly soluble in water, but mixes well with most organic solvents.
-
Thermal stability: It is resistant to heat and does not break down under prolonged exposure to high temperatures.
